In fact, I think that intertwining her childhood episode with the arc where she leaves the jedi order would be the best place to “deposit” these scenes of her as a child, because there is her true farewell to the series. It’s like saying “Hey, this is the last time you’re going to see this character, so let’s show you what’s left to know about her, which is her origin”. That would increase the strength of that arc EVEN MORE, making it even more emotional, in my opinion.
But maybe it’s a little weird to do that due to the difference in CW and TOTJ styles.
Anyway, I just think that the Life and Death episode works so much better being cut as flashback segments distributed in an already established episode/arc of Clone Wars/TOTJ than an episode as itself.
